加载了笔尖文件，但未设置视图出口 [英] Loaded the nib file but the view outlet was not set

问题描述

我意外删除了universityPicker.xib，然后使用相同的名称创建了一个新的文件，但无法建立连接.文件崩溃并显示此消息

I deleted the universityPicker.xib accidentally and then made a new one with the same name but no connection could be done. The file crashes and gives this message

我该如何解决?
